Specification of Letters Patent.

Patented April 23, 1907.

Application filed November?, 1905. Serial No. 285,545.

T all L11/"tom, 111 wml/y concern: Be it known that I, DELBERT COOLEY, a

citizen of the UnitedStates, and a resident of Galena, in the county ofCherokee and State of Kansas, have invented a new and Improved Gas andAir Burner, of which the following is a full, clear, andexactdescription.

. The object of the invention is to provide a new and improved gas andair burner for use in heaters, furnaces, and the like arranged to causea thorough mixing of the gas and air previous to ignition of the mixturewith a view to insure a complete combustion of the mixture, thearrangement also permitting independent regulation of the supply of gasand air according to the richness of` the gas.

The invention consists of novel features and parts and combinations ofthe same,

which will be more fully described hereinafter and thenpointed out inthe claims.

A practical embodiment ofthe invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.Y

Figure 1 is a sectional side elevation of the improvement, andFig. 2 isa perspective view of the gas-valve and the mixing-disk.

The mixing-tube A is adjustably secured said bracket extending from theangular end D of a gas-supply pipe D, connected at the terminal of theangularend D by a pipe E with a suitable gas-supply. Within thegasregulating-valve F3 is provided with aper-` tures F, arranged withinthe gas-supply pipe D, to allow the gas to pass from the same throughthe openings F4 into the gas-regu;D

lating valve F3. The outer portion of the gas-regulating valve F3` ispro vided with lengthwise-extending slots F5, through which the gasescapes from the inside of the valve Fs into the mixing-tube A, asplainly mcli- E cated b v the arrows in Fig. l. On the outer j end ofthe valve F3 is secured a mixing-disk G, extending transversely in thetube A and reaching to the inner wall thereof, the said disk havingangularlydisposed varies to forni spaces between the edges of adjacentvaries for the passage of the gas and air to insure a complete mixturethereof.

The air-entrance end of the mixing-tube A is provided with a flaringmouth' orji'lange A', opposite which is arranged a correspondinglyshapeddisk H, held adjustable on the gassupply pipe D by the use of aset-screw I. Thus by loosening the set-screw I and moving the disk Hneareror farther from the mouth A it is possible to regulate the amountof air passing into the mixing-tube A. By adjusting the rod F lengthwisein' the supply-pipe D, as previously described, an inward or outwardsliding motion is given to the valve F3, so that the slots F5 extendmore quently a minute regulation of the amount of gas passing into themixing-tube A is had. Thus from the foregoin'g it will be seen that theamount of air and gas to be mixed within the tube A can be regulatedindependent one of the other, according to the richness of the gas, toinsure the formation of a properlycombustible mixture of gas and air.

. It is understood that the air passing through the mouth A into themixing-tube A comes in contact and mixes with the gas escaping throughthe slots F5, and this mixture of gas and air passes between theadjacent varies of the disk G, so that a further intimate mixture of thegas and airtakes place, to form a highly-combustible mixture to beburned at the outer end of the mixingtube A. i l The' device is verysimple and durable 1n tively few parts not. liable to 'get easily out oforder. y

Having thus described my invention, I. claim as new and desire to secureby Letters Patent- 1' g 1. A gas and air burner, comprising amixing-tube open at one end for the admission of air and open at theother end for the discharge of the combustible mixture of gas,and air, agas-supply' 'pipe connected with a gassupply and extending into the saidmixingJ tube, a tubular valve adjustable lengthwise in the inner end ofthe said gas-supplypipe, the said valve having gas-inlet openings withorless into the mixing-tube A, and cons'econstruction and is composed ofcomparain the gas-suppbT pipe and slots opening into l the saidmixing-tube, and a mixing-disk E air and open at the other end `for thedisf charge of the combustible mixture of gas and air, a gas-suppl}vvpipe connected with a gassupply and extending into the said mixingtube,a tubular valve adjustable lengthwise in the inner end of the saidgassupply pipe, the said valve having' gas-inlet opening` Within thegas-supplyT pipe and slots opening into the said mixing-tube, amixing-disk Within the mixing-tube having angularlydisposed vanes forthe passage of the gas and air to insure a comple te mixture thereof,and a llanged adjustable disk opposite the flanged air-entrance end ot'the said mixing-tube.

In testimony whereof I have signed my name to this speeiiieation in thepresence of two subscribing Witnesses.

DELBERT COOLEY.
